4liti'fhile thie invention ie intetlc teeee pertierdorljif bett l Gtialso be used for other purposes, such as marking lines at angles of l5degrees, as

. previously stated. The lange 2 is disposed at right anglesr to plate ltransversely thereof so that, by engaging this lanfge over the edgeportion of a board or other work to be operated upon, the lateral edgesof plate l can be employed as straight edges for drawing lines atrightfangles to a board or other work to be cut or operated upon.

As illustrated in Figure 5, the inner face of flange l0 may be providedwith suitable graduations which are to be used with ret'- erenee to theinner end of slide 1l to facilitate use ot' the marking point 17 whenthe thickness of the hinge butts to be used is known.

What I claim is:

1. In a device of the class described, an elongated plate provided atone end with a transversely extending flange, said plate being furtherprovided with a longitudinally extending slot, a carriage slidablymounted on the plate and provided with a rib snugly fitting into saidslot, said carriage having a flange disposed in parallelism with theflange of the pla-te, a member including al body provided with a studextending through the'carriage and the rib thereof, a thumb vnutthreaded on said stud and eoaetingwith said body for securing thecarriage in adjustment longitudinally of the platre, the body ol saidmember being,T provided with another stud. a member harinaT a slotreceiving said second stud at the other` end of the body, said lastmentioned member being confined between said second stud and the flanpgeof the carriage and being movable transversely et the carriage, and athumb nut threaded on the second mentioned stud eo-actinp; with the bodytor securingl the movable member in adjustment, said movable memberbeing provided at one end with a marking clement.

2. A marking' tool includinf an elongated rectangular base plate having;a slot termed longitudinally therein and havin."Y a tlange thereon, saidbase plate having eraduations thereon, a carri age plate slidable onsaid base plate and having a rib thereon disposed in said slot, a flangeportion on said carriage plate parallel with the flange on .said baseplate, a stud member tor adjust ably securingr said ea riage and saidbase plate. and a member havingl an elongated slot and provided with amarkingelement, adapted for adjust ment transversely to said base platesaid .stud member providing means t'or securing said last mentionedmember independently of th(` carriage plate.

In testimony whereof I atiix my signature.
